Sealing systems used for non-metallic rod pneumatic drives have hard duty conditions, including the absence of any kind of lubricant and non-linear thermal regime. Due to this, the wear evolution of the lip -rod pair can be difficult to be estimated.

Each system (stand – driving) and the continuous rolling line to which it belongs have its own functional and energetically parameters. To reduce any faults of the strip surface it is also necessary to check (eventually having a control line) the r
